IMPROVEMENT IN DoR-BELLS.

Specification forming part of Letters Patent No. 202,064, dated April 2, 1878; application filedl i September 24, 1877.

To all whom t may concern:

Be it known that I, JOHN W. SNIDER, a resident of the city of New Orleans, parish of Orleans, and State of Louisiana, have invented a certain new and useful Improvement in Gongs; and I do hereby declare the following to be a full, clear, and correct description of the same, reference being had to the annexed drawing, making a part of this specification.

This invention relates more particularly to the striking apparatus of gongs. Its novel feature consists in dispensing with the use of springs for operating the hammer, and in providing, in lieu of the same, a weight and operating-lever, the latter so arranged as to admit of the apparatus being used either on the right or left of the pull, as the occasion may requlre.

In order that my invention may be fully understood, reference must be had to the drawing, whereon- Figure l represents a front view of my invention complete. Fig. 2 is a front view, With gong and guard removed, in order to exhibit the workin g parts of the apparatus, while Fig. 3 is a perspective view of the operatingweight.

This invention consists of a gong, A, which is secured to a curved strap or guard, B, as shown at C. The ends of this. strap are turned inward and secured by rivets or screws to a plate, D, having its corners perforated for the reception of screws or nails7 by which means the apparatus is designed to be permanently secured in any desired locality.

On 011e side of the strap B is secured to the face of the plate D a knocker or casin g, F, in which operates a weight, G, the said weight of the plate D, in order to provide for the ap` paratus being placed on either side of the pull. v

One end of the aforesaid bell-crank is connected with the pull by means of a wire, r, while its other end is furnished with a toot-hed sector, fr, for engaging in a rack that is cast at the edge of the weight, as shown at t.

The circular opening U in the plate D serves in a measure to lighten th`e same. Its main object, however, is to afford a means for inl troducin g a wrench or screw-driver in the rear ofthe gong for loosening or tightening the screw by which it is supported on the strap.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In combination with a gong, A, strap B, plate D, and casing F, a weight, Gr, hammerlever m, andl bell-crank O, as described, and for the purpose specified.

In testimony whereof I have hereunto set my hand.

JOHN W. SNIDER.
